The Importance of Continued Maintenance of Coal-Fired Power Stations

Overview of the Importance of Continued Maintenance of Coal-Fired Power Stations

Globally there has been a significant focus and transition towards clean and renewable energy sources, with coal-fired power stations coming under intense scrutiny. While the transition to cleaner energy alternatives is a goal, it is essential to acknowledge that several practical considerations and challenges impact this transition, as is the case when examining South Africa’s current power mix. The below opinion piece sheds light on the need to maintain South Africa’s coal-fired power stations while identifying and planning the transition to cleaner energy sources.

Baseload Power

One of the pressing reasons to prioritise the maintenance of coal-fired power stations in South Africa is the ongoing issue of load shedding caused by ageing infrastructure. With an ageing power grid, the country faces immense challenges in providing a consistent and reliable electricity supply. Currently, this conventional energy cannot meet the growing demands of its population and industries. You may be asking what the solution is, and the answer lies in effective and continued maintenance.

South Africa can mitigate load shedding by ensuring the continued maintenance of the country’s coal-fired power stations. The lack of constant maintenance has resulted in several power station breakdowns, malfunctions and failures, putting immense pressure on the grid.

When these power stations are regularly maintained, they can ensure power stability by providing reliable baseload power. The consistent generation capacity of coal-fired power stations would thus alleviate the strain on the grid during peak demand periods.

Investing in the consistent maintenance of coal-fired power stations also allows for identifying and rectifying infrastructure weaknesses. Regular maintenance activities can help detect and address potential issues before they escalate, extending the lifespan of these power stations and optimising their operational efficiency. This consistent maintenance ensures optimal power-generating capacity.

Transition from Coal-Fired Power Stations to Renewable Energy Challenges

While transitioning to cleaner energy sources is an important long-term goal, the continued maintenance of coal-fired power stations remains crucial in the short to medium term. Coal-fired power stations offer a practical and effective solution to address load shedding and bridging the gap until more sustainable and reliable alternatives can be fully integrated into South Africa’s energy infrastructure.

It should be noted that the transition from coal to renewable energy sources is a complex and multifaceted process. This will require significant investments in infrastructure, grid modernisation, and human resources, which is currently not feasible for many countries, including South Africa.

We are in a catch-22 situation where we know that renewable energy generation is needed and that it will be able to assist with power generating capacity. However, the country does not have the capital to invest in a large-scale renewable energy solution. It is, therefore, critical to ensure that the coal-fuelled power supply that we rely on is running at its optimal efficiency and that maintenance planning is carried out with the proper planning. If this fails to occur, it could lead to further energy shortages, price volatility and various socio-economic problems.

Technological Advancements

One of the main reasons for the move towards renewable energy sources is that coal-fired power stations are associated with environmental concerns. There have, however, been significant strides made in the development of cleaner coal technologies. Advanced systems like ultra-supercritical and integrated gasification combined cycle (IGCC) plants reduce emissions and improve efficiency. Research and development in carbon capture, utilisation, and storage (CCUS) technologies hold the potential to mitigate the environmental impact of coal-fired power generation. Maintaining existing coal-fired power stations while investing in cleaner technologies and promoting sustainable practices can be a pragmatic approach towards reducing short- to medium-term emissions.


Transitioning to cleaner energy sources is crucial for mitigating climate change and achieving a sustainable future. However, we must recognise the complexities and challenges associated with this transition, particularly in South Africa, where we depend heavily on coal-fired power stations. While the long-term goal should be a complete phase-out of coal, maintaining these power stations in the short to medium term can provide reliable baseload power, reducing load shedding.
